i just had injectors replaced in my 06 dodge about 6000 miles ago and i think they are going bad. it blows a little white smoke when its cold out for a few seconds and goes away. but it only does it when its cold out. it never did do that last winter when it was cold out.

 

should be a flash for that

 

a little white smoke at first when its cold is ok if it goes away. you should get a 2mic fuel filter while those injectors only have 6k miles on them...
